A witch’s curse, a thwarted courtship, an assumed identity and the irksome business of committing daily acts of wickedness. Opera Holland Park and Charles Court Opera reunite for a scintillatingly silly co-production of Gilbert and Sullivan’s comic opera, Ruddigore, lampooning etiquette books and the Victorian obsession with the supernatural. John Savournin directs and sings the role of Sir Despard Murgatroyd, leading a splendid cast of G&S stalwarts and fresh talent.
